" Leam Patent No.. 92,479, dated .my 13, 1869.

IMPROVE DoUGrH-KNBADER The chcdlo referred to in these Letters Patent and making part of the name.

To all whom lit may conce/m Be it known that LCHARLES B. SAWYER, of the town of Fitchburg, in the county of Worcester, and

State of Massachusetts,have invented a new and useful Improvement in Machines for Kneading Dough for Bread; andI do hereby declare that the following is a full, clear, and exact description of the. same, reference being had to the accompanying drawings, making part ot' this specification, in which- Eigure 1 is a perspective view of a. kneading-machine which embodies my improvement. l

Figure 2 is a cap-piece for covering the set of gea-rwheels at the top of the machine.

My said invention consists oi' a revolving receptacle for the constituent materials of the dough, and a compound stirrer or kneading-device consisting of two vertical rollers, which, by moving in opposite directions to each other in the receptacle, which also re- Ivolves, the bread-material is irst thoroughly mingled,

and then, by the revolving action mentioned, carried in two currents or moving bodies around the rollers, and are thus thoroughly worked into each other and kneaded to the proper consistency for baking to form bread.

To enable others to make and use my4 invention, I will proceed to describe the construction and operation of the same.

In the drawing- 'A A is an upright frame, within which the moving parts are arranged and' operate. These consist of a dish or receptacle H, which may be made of sheet-v metal, and is secured on a revolving plat-e, S, at the bottom, which, by means of one or more grooves and the band n, running on its periphery, and upon a pnlley, a, on the crank-shaft D, revolves the said receptacle in the direction indicated by arrows.

E and G are the stirrers, which are best made of glass or porcelain, in the form of two plain cylinders that extend with their free ends to the bottom off-fthe receptacle, and are supported and revolve in a vertical position in bearings formed in the cross-pieces A A of the frame, by motion communicated by thetrain of gear-wheels from the crank-shaft D,- the movement of the said rollers being indicated by the arrows on cach; and the said stirrers are arranged relatively with (i,

the receptacle, as shown in the plan or diagram' of' the sameexhibited in iiga. The stirrer G, being close to the side of the receptacle, revolving in the direction indicated by arrows, the dough is carried around until it meets the rollers E G, the latter, G, of which causes the dough to cleave from the side of the receptacle, and pass between the two rollers, which revolve more rapidly than the receptacle, so that each roller carries the mass of dough next to it in twobodies, as shown by the direction of the arrows, which are repeatedly mingled with and worked into each other, and rapidly kneaded until of the desired consistency, which, for an ordinary batch of bread, for family use, requires from three to five minutes.

Claim.

' Having described my invention,

XVhat I claim, and desire to secure by Letters Pat\ ent, is-

rlvhe improved kneading-machine herein described, consisting of the revolving pan H, the mixers E and G, and the crankshaft D, with the necessary framework and supports, the, whole arranged and operating substantially as set forth, for the purposes specified.
